A. RO ULEAU CORNER CONSTRUCTION FOR BED SPRINGS Filed June 22, 1942 Patented July 18, 1944 Armini Rouleau, Granby, Quebec, Canada Application June 22,1942, Serial No. 443,041 In Canada January 9, 1942 6 Claims.

This invention relates to improvements inbed spring frames, the object being to provide a generally improved frame including exceptionally light and strong corner brackets made of band steel, said brackets being adapted by the construction and arrangement thereof to withstand, without distortion, heavy shocks as well as the most severe strains or stresses likely to be imposed thereon by tensioning of the spring fabric;

Other objects, advantages and characteristic features of the invention will be more readily apparent from the following detailed description and accompanying drawing, in which Fig. 1 is a side elevational view of a bed spring embodying my invention.

Fig. 2 is an end view of the assembly shown in Fig. 3 is a sectional view taken substantially along the line 33 of Fig. 1.

Fig. 4 is a sectional view taken substantially along the line -44 of Fig. 3.

Fig. 5 is a fragmentary side elevationalview of a slight modification.

In this drawing I have shown a bed spring frame comprising upper transversely extending end frame members 5, lower longitudinally extending side frame members 6, corner members 1 and spring fabric 8, the latter being stretched between the end members 5.

According to this invention the main part of each corner bracket is made of band steel or other bendable metal and is fabricated so that it presents relatively offset upper and lower end portions 9 and Ill joined together by an inclined intermediate portion I I. In the completed rame the upper end portion 9 of each bracket is attached to one of the upper transverse frame members 5 to which the spring fabric 8 is anchored. The lower end portion of the bracket is inwardly offset toward the transverse centre of the frame and is attached to one of the lower longitudinal frame members 6. Each bracket therefore presents an intermediate portion II which inclines upwardly and outwardly from the lower end portion ID to the upper end portion 9. By reason of this inclination of the intermediate portion ll each bracket 1 is thus well adapted to resist stresses imposed thereon by heavy tensioning of the spring fabric 8.

In the construction shown in Figs. 1 to 4 inelusive, the main portion of each bracket 1 is formed by bending a strip of band steel to provide two arms l2 and I3 which form the intermediate portion ll of the bracket and converge toward their free end portions l4 and I5 which are bent to extend vertically in parallel relation with each other to form the upper end portion 9 which is riveted to one of the end frame members 5 as indicated at [6. The lower end of the outer arm l3 merges with a vertically extending portion I! which is joined by an upwardly and inwardly inclined portion I8 to the lower end of the inner arm l2, the portions l1 and I8 forming the aforesaid lower end portion ID of the bracket. The cylindrical frame members 6 pass through openings formed in the inclined lower portions l8 of two opposing brackets l and abut against the inner surfaces of the vertical portions ll of said brackets. ,The portion I! of each bracket 1 has riveted thereto a laterally projecting lug 29 provided with a circular opening 2| in which the adjacent end of one of the tubular frame members 6 is fitted.

The portions of the lugs whichproject beyond the bracket 1 are recessed as at Net to fit over the side rails of the bedstead on which the bed spring is to be supported, the recessing of said lugs alTording a shoulder 22 which abuts the bedstead rail to prevent lateral sliding of the spring frame relative thereto.

Turning movement of each tubular frame member 6 relative to its supporting brackets l is prevented by rivets 24 connecting the portions I2 and I1 of the brackets, intermediate portions of said rivets being passed through slots 25 provided in the end portions of the members 6. The rivets 24 not only prevent turning movement of the frame member 6 but also act as connecting members between the portions I2 and 11 of each bracket to prevent separation of these portions by shocks or strains to which the brackets are subjected in service.

The portions of lugs 20 which project beyond the brackets I may be connected to the lower end frame members 5 by strengthening braces 28.

The arm I2 of each bracket is preferably curved or arched in cross section as indicated at whereby said arm is strengthened to prevent folding or collapsing thereof under heavy shocks and strains.

In Fig. 5 I have shown a slight modification in which the lower end of arm l3 merges with a vertical portion 32 which, in turn, is connected by a horizontal portion 33 to a vertical portion 34 which merges with the lower end of the arm H. In this case the tubular member 6 extends through an opening in the vertical portion 34 and is butted against the inner surface of the vertical portion 32. A lug 36 corresponding to the lug 20 is riveted as at 31 to the vertical portion Having thus described my invention, whatI,

claim is:

1. A bed spring comprising upper transversely extending end members, lower longitudinally extending side members, spring fabric stretched be- I tween said end members and corner members connecting the end members to the ends of the side members, each corner member consisting of a strip of metal bent to provide relatively olfset upper and lower end portions joined together by an inclined intermediate portion, the upper end portion of each corner member being constituted by flatly engaged, parallel, vertically extending terminal portions of said strip and being attached to a vertical side surface of one of said upper transverse frame members so that the lower end portion of said bracket or corner member is offset inwardly toward the transverse centre of the frame, the intermediate portion of each corner member comprising spaced arm portions which converge from the lower toward the upper end portion of said member, and the lower end portion of each corner member comprising a vertically extending portion merging with the outer arm of said member and an upwardly and inwardly inclined portion connecting said vertically extending portion to the lower end of the inner arm of said member, said upwardly and inwardly inclined portionbeing provided with an opening through which the end of one of the side memhers is extended into abutting engagement with the inner face of said vertically extending portion.

2. A bed spring as set forth in claim 1, in which the lower end portion of each corner member comprises a vertically extending portion merging with the outer arm of said member and an upwardly and inwardly inclined portion connecting said vertically extending portion to the lower end of the inner arm of said member, said upwardly and inwardly inclined portion being provided with an opening through which the end of one of the side members is extended into abutting engagement with the inner face of said vertically extending portion, and a rivet connecting the inner arm of the corner member to said vertically extending portion, said rivet passing through a slot in the adjacent end of said side member.

3. A corner member for bed springs comprising a strip of metal bent to provide upwardly converging arm portions which are inclined to the vertical and are extended at their upper converging ends to provide vertically extending parallel' portions, the outer of said arm members merging at its lower end with a vertically extending portion which is connected by an in-' wardly and upwardly inclined portion to the lower end of the inner arm portion of said member, said upwardly and inwardly inclined portion having an opening formed therein.

4. A corner member as set forth in claim 3 including a lug attached to the inner surface of said vertically extending portion and projecting laterally beyond the same.

5. A corner member as set forth in claim 3 including a lug attached to the inner surface of said vertically extending portion and projecting laterally beyond the same, and a rivet connecting said vertically extending portion to the lower extremity of the inner arm portion of said member.

6. A corner member as set forth in claim 3 including a lug attached to the inner surface of said vertically extending portion and projecting laterally beyond the same, said lug being pro vided with'an opening in line with the opening in said upwardly and inwardly 'inclinedportio'n.
